AUTOMATIC LAMP-EXTINGUISH ER.

SPECIFICATION forming part of Letters Patent No. 516,868, dated March 20, 1894.

Application filed May 17, 1893.

To all whom it may concern.-

Be it known that I, MATTHEW MAOELREE, a citizen of the United States, residingin the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvementin AutomaticLamp Extinguishers, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a device substantially as described for automatically extinguishing the flame of a lamp in the event of overturning of the latter.

Figures 1 and 2 represent vertical sections of a lamp extinguisher embodying my invention.

Similar letters of reference indicate corresponding parts in the two figures.

Referring to the drawings: A designates portion of a lamp, and B designates a sliding sleeve on the wick tube thereof. Connected with said sleeve is a head E, which occupies the chamber F below the wick tube. In the present case, the vapor-discharging tube 0 is employed as the medium of connection of the head E and sleeveB, said tube having a vent D therein for evident purposes. On the side of the chamber F is a deflector G, whereby the wick is prevented from entering the chamber F, without however being interfered with in its raising and lowering motions. v

In the chamber F below the'head E, is a head H, which is seated on the base of said chamber, and has depending from it the weight J, whose sustaining arm K passes freely through an opening in said base and is connected with said head H. v

The operation is as follows: When the lamp is in use and ignited, the sleeve B in no wise interferes with the wick tube, but when the lamp is overturned, the weight acts on the head I-I so as to oscillate the same, moving it Serial No. 474,499. (No model.)

on its seat in the guide F, and causing said head to press the head E, whereby the sleeve B is pushed over the wick tube, so as to inclose the ignited portion of the wick, thus quickly extinguishing the flame.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An automatic lamp extinguisher consisting of a tubular sleeve vertically movable on the wick tube of a lamp and adapted to be raised above the top thereof and having a head connected with its lower end, a head below said sleeve head provided with a depending Weight, a chamber in which said heads move having an upper wall forming a deflector for the lamp wick, said parts-being combined substantially as described.

2. An automatic lamp extinguisher consisting of a tubular sleeve movable on the wick tube of a lamp and adapted to be raised thereon above the top of the same, a vapor discharging tube connected with said sleeve, a head connected with the lower end of said tube, a head below said sleeve head having a MATTHEW MAOELREE.
